Abstract

Vehicular ad hoc networks have emerged as a promising approach to increasing road safety and efficiency. Vehicles periodically broadcast traffic-related status messages. Message authentication is a common way for ensuring information reliability, but it is an unaffordable computational cost for single vehicle. In this article, we propose an efficient cooperative message authentication based on reputation mechanism. In the proposed scheme, reputation model is used to assess authentication efforts of vehicles, which enhances initiative for cooperative message authentication and inhabits selfish behavior; sequence optimization algorithm solves messages overflowing on condition limited computation of onboard unit and improves the speed of message authentication at the premise of ensuring the reliability of message authentication. Simulation results show that our scheme presents a nice performance of authentication efficiency, packet loss ratio, and missing detection ratio.

Summary

Introduction

Vehicular ad hoc networks (VANETs) have been aroused great attention and promising research from academia, industry, and governments in recent years. To the best of our knowledge, it assumes that vehicles will selflessly and actively take part in message authentication in most of existing cooperative authentication scheme.[5] the vehicles are the member of a community and are unwilling to actively participate in message authentication or do false authentication because that cooperative authentication will result in loss of privacy and resource consumption.[6] it is an idealized model for vehicles to selflessly take part in cooperative message authentication. We propose a cooperative message authentication scheme based on reputation mechanism. In this scheme, the reputation model is proposed to evaluate the efforts of cooperative message authentication and message authentication sequence optimization algorithm is proposed to resolve messages overflowing vehicles.
